Motorola has posted Moto G4 Factory Image and has deleted all the past builds of the same. The Moto G4 is currently the only device with an official factory image available for download. The Moto G4 Plus is also not listed right now.
Moto G4 users can now flash this factory image to restore their devices Android 6.0.1. If anyone defaulted the flashing of custom ROM or rooting on Moto G4, they can flash this factory image to get out of any of these problems.
Motorola is actually handling images a little differently now. You just select the device and download the image.
So without any difficulty download your device’s factory image.
